DETAILED DESCRIPTION

The present invention will now be described more specifically with reference to the following embodiments. It is to be noted that the following descriptions of different embodiments of this invention are presented herein for purpose of illustration and description only, and it is not intended to limit the scope of the present invention.

Please refer to FIG. 1A, FIG. 1B, and FIG. 1C, according to one or some embodiments of the present invention, a vacuum cleaner for air pollution prevention is provided. The vacuum cleaner has a basic function of dust-cleaning and further has a function of air pollution prevention. The vacuum cleaner includes a main body 1, a blower 2, a filtering and cleaning assembly 3, at least one gas detection module 4, and a micro-controller 5. The main body 1 is configured to form a flow-guiding path L. The blower 2 is disposed in the flow-guiding path L to guide the air convection. The filtering and cleaning assembly 3 is disposed in the flow-guiding path L to filter and clean an air pollution source in the air guided by the blower 2. The at least one gas detection module 4 is disposed in the flow-guiding path L to detect the air pollution source and transmit a gas detection data. The micro-controller 5 wirelessly receives the gas detection data of the at least one gas detection module 4 and performs an intelligent comparison under a surveillance condition so as to transmit a driving command to enable the blower 2 and adjust the air volume of the blower 2. In one aspect of the present invention, the surveillance condition is defined as the gas detection data of the air pollution source detected by the at least one gas detection module 4 exceeds a safety detection value.

It is noted that, the blower 2 is a centrifugal-type blower, but is not limited thereto. Any blower 2 can be an extended example of the embodiments of the present invention provided the blower capable of generating air flow. Moreover, it is noted that, according to the instant invention, the filtering and cleaning assembly 3 may be placed before or behind the gas detection module 4. For example, in the embodiment shown in FIG. 1A, after the gas-flow is introduced into the main body 1 by the blower 2, the gas-flow firstly passes through the filtering and cleaning assembly 3 and then is detected by the gas detection module 4; in another embodiment, after the gas-flow is introduced into the main body 1 by the blower 2, the gas-flow will be detected first by the gas detection module 4 and then passes through the filtering and cleaning assembly 3 (not shown in the figure). These embodiments are all within the scopes of the present invention. Moreover, it is noted that, after the micro-controller 5 wirelessly receives the gas detection data detected by the gas detection module 4, the micro-controller 5 performs an intelligent comparison to transmit the driving command to enable the blower 2 or adjust the air volume of the blower 2. Therefore, when the gas detection data is much larger than the safety detection value, the micro-controller 5 adjusts the air volume of the blower 2 to be much larger; while when gas detection data is much closer to the safety detection value, the micro-controller 5 adjusts the air volume of the blower 2 to be much smaller.

As shown in FIG. 3 to FIG. 9A, the gas detection module 4 includes a control circuit board 41, a gas detection main body 42, a microprocessor 43, and a communication device 44. The gas detection main body 42, the microprocessor 43, and the communication device 44 are integrally packaged with the control circuit board 41 and electrically connected to each other. The microprocessor 43 controls the operation of the gas detection main body 42, the gas detection main body 42 detects the air pollution source and outputs a detection signal, and the microprocessor 43 receives the detection signal so as to compute, process, and output the detection signal, therefore the microprocessor 43 of the gas detection module 4 generates the gas detection data and provides the communication device 44 with the gas detection data for transmitting outwardly. Moreover, in some embodiments, the outward communication transmission of the communication device 44 may be implemented through a bidirectional wired transmission. For example, the wired transmission may be achieved by a USB port, a mini-USB port, and micro-USB port. Alternatively, in some embodiments, the outward communication transmission of the communication devices 44 may also be implemented through a bidirectional wireless transmission. For example, the wireless transmission may be achieved by a Wi-Fi module, a Bluetooth module, a radiofrequency identification module, and a near field communication module. The micro-controller 5 wirelessly receives the gas detection data transmitted by the communication device 44.

Please refer to FIG. 4C, FIG. 5A, FIG. 5B, FIG. 6 , FIG. 7A, and FIG. 7B. In one or some embodiments, the gas detection main body 42 includes a base 421, a piezoelectric actuator 422, a driving circuit board 423, a laser component 424, a particulate sensor 425, an outer cover 426, and a gas sensor 427. The base 421 has a first surface 4211, a second surface 4212, a laser installation region 4213, a gas inlet groove 4214, a gas-guiding component installation region 4215, and a gas outlet groove 4216. The first surface 4211 and the second surface 4212 are opposite to each other. The laser installation region 4213 is formed by hollowing out the base 421 from the first surface 4211 to the second surface 4212 for accommodating the laser component 424. The outer cover 426 covers the base 421 and has a side plate 4261. The side plate 4261 has a gas inlet opening 4261 a and a gas outlet opening 4261 b. The gas inlet groove 4214 is recessed from the second surface 4212 and located adjacent to the laser installation region 4213. The gas inlet groove 4214 has a gas inlet through hole 4214 a and two lateral walls. The gas inlet through hole 4214 a is in communication with the outside environment of the base 421 and is corresponding to the gas inlet opening 4261 a of the outer cover 426. Two light penetration windows 4214 b penetrate the two lateral walls of the gas inlet groove 4214 and are in communication with the laser installation region 4213. Therefore, when the first surface 4211 of the base 421 is covered by the outer cover 426, and the second surface 4212 of the base 421 is covered by the driving circuit board 423, a gas inlet path can be defined by the gas inlet groove 4214.

Please refer to FIG. 6 . The gas-guiding component installation region 4215 is recessed from the second surface 4212 and in communication with the gas inlet groove 4214. A ventilation hole 4215 a penetrates a bottom surface of the gas-guiding component installation region 4215. Each of the four corners of the gas-guiding component installation region 4215 has a positioning bump 4215 b. The gas outlet groove 4216 has a gas outlet through hole 4216 a, and the gas outlet through hole 4216 a is corresponding to the gas outlet opening 4261 b of the outer cover 426. The gas outlet groove 4216 includes a first region 4216 b and a second region 4216 c. The first region 4216 b is recessed from a portion of the first surface 4211 corresponding to a vertical projection region of the gas-guiding component installation region 4215. The second region 4216 c is at a portion extending from a region that is not corresponding to the vertical projection region of the gas-guiding component installation region 4215, and the second region 4216 c is hollowed out from the first surface 4211 to the second surface 4212. The first region 4216 b is connected to the second region 4216 c to form a stepped structure. Moreover, the first region 4216 b of the gas outlet groove 4216 is in communication with the ventilation hole 4215 a of the gas-guiding component installation region 4215, and the second region 4216 c of the gas outlet groove 4216 is in communication with the gas outlet through hole 4216 a. Therefore, when the first surface 4211 of the base 421 is covered by the outer cover 426 and the second surface 4212 of the base 421 is covered by the driving circuit board 423, a gas outlet path can be defined by the gas outlet groove 4216 and the driving circuit board 423.

Furthermore, the laser component 424 and the particulate sensor 425 are disposed on the driving circuit board 423 and located in the base 421. The laser component 424 and the particulate sensor 425 are electrically connected to the driving circuit board 423. It should notice that the driving circuit board 423 is omitted to clearly explain the positions of the laser component 424, the particulate sensor 425, and the base 421. In the embodiment of the present invention, the laser component 424 is located at the laser installation region 4213 of the base 421. The particulate sensor 425 is located at the gas inlet groove 4214 of the base 421 and aligned with the laser component 424. Moreover, the laser component 424 is corresponding to the light penetration windows 4214 b so as to allow the light beam emitted by the laser component 424 to pass therethrough and into the gas inlet groove 4214. The light path of the light beam emitted by the laser component 424 passes through the light penetration windows 4214 b and is orthogonal to the gas inlet groove 4214. The light beam emitted by the laser component 424 passes into the gas inlet groove 4214 through the light penetration windows 4214 b, thereby the particulate matters in the gas inlet groove 4214 is illuminated by the light beam. When the light beam illuminates on the particulate matters, the light beam will be scattered and generate light spots. Hence, the light spots generated by the scattering are received and calculated by the particulate sensor 425 located at the position orthogonal to the gas inlet groove 4214 to obtain the detection data of the gas. Furthermore, the gas sensor 427 is disposed on the driving circuit board 423 and is located at the gas outlet groove 4216 for detecting the polluted gas introduced into the gas outlet groove 4216, and the gas sensor 427 is electrically connected to the driving circuit board 423. In one embodiment of the present invention, the particulate sensor 425 is provided for detecting the information of particulate matters, and the gas sensor 427 includes at least one selected from the group consisting of a volatile organic compound detector capable of detecting gas information of carbon dioxide (CO₂) or total volatile organic compounds (TVOC), a formaldehyde sensor capable of detecting gas information of formaldehyde (HCHO) gas, a bacterial sensor capable of detecting information of bacteria or fungi, and a virus sensor capable of detecting information of viruses, a temperature and humidity sensor capable of detecting the temperature and humidity of the gas, and any combination thereof.

Please refer to FIG. 7A and FIG. 7B. The piezoelectric actuator 422 is located at the gas-guiding component installation region 4215 with square-shaped of the base 421, and the gas-guiding component installation region 4215 is in communication with the gas inlet groove 4214. When the piezoelectric actuator 422 is enabled, the gas in the gas inlet groove 4214 is inhaled passing through the ventilation hole 4215 a of the gas-guiding component installation region 4215, and entering the gas outlet groove 4216. Moreover, the driving circuit board 423 covers the second surface 4212 of the base 421. The laser component 424 and the particulate sensor 425 are disposed on the driving circuit board 423 and electrically connected to the driving circuit board 423. As the outer cover 426 covers the base 421, the gas inlet opening 4261 a is corresponding to the gas inlet through hole 4214 a of the base 421, and the gas outlet opening 4216 b is corresponding to the gas outlet through hole 4216 a of the base 421.

Please refer to FIG. 8A and FIG. 8B. The piezoelectric actuator 422 includes a nozzle plate 4221, a chamber frame 4222, an actuation body 4223, an insulation frame 4224, and a conductive frame 4225. The nozzle plate 4221 is made by a flexible material and has a suspension sheet 4221 a and a hollow hole 4221 b. The suspension sheet 4221 a is a flexible sheet that can bend and vibrate. The shape and the size of the suspension sheet 4221 a is approximately corresponding to the inner edge of the gas-guiding component installation region 4215. The hollow hole 4221 b penetrates through the center portion of the suspension sheet 4221 a for the gas flowing therethrough. In one embodiment of the present invention, the shape of the suspension sheet 4221 a can be selected from square, circle, ellipse, triangle, or polygon.

Furthermore, the chamber frame 4222 is stacked on the nozzle plate 4221, and the shape of the chamber frame 4222 is corresponding to the shape of the nozzle plate 4221. The actuation body 4223 is stacked on the chamber frame 4222. A resonance chamber 4226 is collectively defined between the actuation body 4223, the nozzle plate 4221, and the suspension sheet 4221 a. The insulation frame 4224 is stacked on the actuation body 4223. The appearance of the insulation frame 4224 is similar to the appearance of the nozzle plate 4221. The conductive frame 4225 is stacked on the insulation frame 4224. The appearance of the conductive frame 4225 is similar to the appearance of the insulation frame 4224. The conductive frame 4225 has a conductive pin 4225 a and a conductive electrode 4225 b. The conductive pin 4225 a extends outwardly from the outer edge of the conductive frame 4225, and the conductive electrode 4225 b extends inwardly from the inner edge of the conductive frame 4225.

Moreover, the actuation body 4223 further includes a piezoelectric carrying plate 4223 a, an adjusting resonance plate 4223 b, and a piezoelectric plate 4223 c. The piezoelectric carrying plate 4223 a is stacked on the chamber frame 4222, and the adjusting resonance plate 4223 b is stacked on the piezoelectric carrying plate 4223 a. The piezoelectric plate 4223 c is stacked on the adjusting resonance plate 4223 b. The adjusting resonance plate 4223 b and the piezoelectric plate 4223 c are accommodated in the insulation frame 4224. The conductive electrode 4225 b of the conductive frame 4225 is electrically connected to the piezoelectric plate 4223 c. In one preferred embodiment of the present invention, the piezoelectric carrying plate 4223 a and the adjusting resonance plate 4223 b are both made of conductive material(s). The piezoelectric carrying plate 4223 a has a piezoelectric pin 4223 d. The piezoelectric pin 4223 d and the conductive pin 4225 a are in electrical connection with a driving circuit (not shown) of the driving circuit board 423 to receive a driving signal (which may be a driving frequency and a driving voltage). The piezoelectric pin 4223 d, the piezoelectric carrying plate 4223 a, the adjusting resonance plate 4223 b, the piezoelectric plate 4223 c, the conductive electrode 4225 b, the conductive frame 4225, and the conductive pin 4225 a may together generate an electrical circuit for transmitting the driving signal, and the insulation frame 4224 is provided for electrically insulating the conductive frame 4225 from the actuation body 4223 to avoid short circuit, thereby the driving signal can be transmitted to the piezoelectric plate 4223 c. When the piezoelectric plate 4223 c receives the driving signal, the piezoelectric plate 4223 c deforms owing to the piezoelectric effect, and thus the piezoelectric carrying plate 4223 a and the adjusting resonance plate 4223 b are driven to vibrate reciprocatingly.

Moreover, the adjusting resonance plate 4223 b is disposed between the piezoelectric plate 4223 c and the piezoelectric carrying plate 4223 a as a cushion element so as to adjust the vibration frequency of the piezoelectric carrying plate 4223 a. Generally, the thickness of the adjusting resonance plate 4223 b is greater than the thickness of the piezoelectric carrying plate 4223 a. The thickness of the adjusting resonance plate 4223 b may be modified to adjust the vibration frequency of the actuation body 4223. The nozzle plate 4221, the chamber frame 4222, the actuation body 4223, the insulation frame 4224, and the conductive frame 4225 are sequentially stacked and assembled and are positioned in the gas-guiding component installation region 4215, thereby a clearance 4221 c is defined between the suspension sheet 4221 a and the inner edge of the gas-guiding component installation region 4215 for the gas to pass therethrough.

A gas flow chamber 4227 is formed between the nozzle plate 4221 and the bottom surface of the gas-guiding component installation region 4215. The gas flow chamber 4227 is in communication with the resonance chamber 4226 formed between the actuation body 4223, the chamber frame 4222, and the suspension sheet 4221 a through the hollow hole 4221 b of the nozzle plate 4221. In one aspect of the present invention, the resonance chamber 4226 and the suspension sheet 4221 a can generate the Helmholtz resonance effect to improve the transmission efficiency of the gas through controlling the vibration frequency of the gas in the resonance chamber 4226 to be close to the vibration frequency of the suspension sheet 4221 a. When the piezoelectric plate 4223 c moves in a direction away from the bottom surface of the gas-guiding component installation region 4215, the piezoelectric plate 4223 c drives the suspension sheet 4221 a of the nozzle plate 4221 to move in the direction away from the bottom surface of the gas-guiding component installation region 4215 correspondingly. Hence, the volume of the gas flow chamber 4227 expands dramatically, therefore the internal pressure of the gas flow chamber 4227 decreases and creates a negative pressure, drawing the gas outside the piezoelectric actuator 422 to flow into the piezoelectric actuator 422 through the clearance 4221 c and enter the resonance chamber 4226 through the hollow hole 4221 b, thereby increasing the gas pressure of the resonance chamber 4226 and thus generating a pressure gradient. When the piezoelectric plate 4223 c drives the suspension sheet 4221 a of the nozzle plate 4221 to move toward the bottom surface of the gas-guiding component installation region 4215, the gas inside the resonance chamber 4226 is pushed to flow out quickly through the hollow hole 4221 b to further push the gas inside the gas flow chamber 4227, thereby the converged gas can be quickly and massively ejected out of the gas flow chamber 4227 through the ventilation hole 4215 a of the gas-guiding component installation region 4215 in a state closing to an ideal gas state under the Benulli's law.

Therefore, through repeating the steps as shown in FIG. 9B and FIG. 9C, the piezoelectric plate 4223 c can bend and vibrate reciprocatingly. Further, after the gas is discharged out of the resonance chamber 4226, the internal pressure of the resonance chamber 4226 is lower than the equilibrium pressure due to the inertia, as a result, the pressure difference guides the gas outside the resonance chamber 4226 into the resonance chamber 4226 again. Therefore, through controlling the vibration frequency of the gas in the resonance chamber 4226 to be close to the vibration frequency of the piezoelectric plate 4223 c, the resonance chamber 4226 and the piezoelectric plate 4223 c can generate the Helmholtz resonance effect so as to achieve effective, high-speed, and large-volume gas transmission of the gas.

Moreover, as shown in FIG. 10A to FIG. 10C, the gas enters the gas detection main body 42 from the gas inlet opening 4261 a of the outer cover 426, flows into the gas inlet groove 4214 of the base 421 through the gas inlet through hole 4214 a, and reaches the position of the particulate sensor 425. Furthermore, the piezoelectric actuator 122 continuously drives the gas into the gas inlet path so as to facilitate the gas inside the detection main body 42 to stably and quickly pass through the particulate sensor 425. Next, the light beam emitted by the laser component 424 passes through the light penetration windows 4214 b, enters the gas inlet groove 4214, and illuminates the gas in the gas inlet groove 4214 which passes through the particulate sensor 425. When the light beam illuminates on the particulate matters in the gas, the light beam will be scattered and generate light spots. The particulate sensor 425 receives and calculates the light spots generated by the scattering to obtain the information of the particulate matters in the gas such as the particle size and the number of the particulate matters. Moreover, the gas passing through the particulate sensor 425 is continuously introduced into the ventilation hole 4215 a of the gas-guiding component installation region 4215 by the piezoelectric actuator 422 and enters the gas outlet groove 4216. Finally, after the gas enters the gas outlet groove 4216, since the piezoelectric actuator 422 continuously delivers the gas into gas outlet groove 4216, therefore the gas is continuously pushed and discharged out of the gas detection main body 42 through the gas outlet through hole 4216 a and the gas outlet opening 4261 b.

Please refer to FIG. 1C. The filtering and cleaning assembly 3 may be the combination of various embodiments. In one embodiment, the filtering and cleaning assembly 3 may be an activated carbon 31, or a high-efficiency particulate air (HEPA) filter 32, or a combination of the activated carbon 31, the high-efficiency particulate air filter 32, and a zeolite mesh 33. In some embodiments, a cleansing factor layer having chlorine dioxide is coated on the activated carbon 31 or the high-efficiency particulate air filter 32 for suppressing viruses, bacteria, fungus, influenza A virus, influenza B virus, Enterovirus, and Norovirus in the polluted gas introduced into the filtering and cleaning assembly 3. Accordingly, the suppressing rate may exceed 99%, allowing the reduction of the cross infections of the viruses. In some other embodiments, a herbal protection coating layer including the extracts of Rhus chinensis Mill (may be Rhus chinensis Mill from Japan) and the extracts of Ginkgo biloba may be coated on the activated carbon 31 or the high-efficiency particulate air filter 32 to generate a herbal protection anti-allergy filter which can efficiently perform an anti-allergy function and destroy cell surface proteins of influenza viruses (e.g., influenza virus subtype H1N1) passing through the herbal protection anti-allergy filter. Alternatively, in some other embodiments, a layer of silver ions may be coated on the activated carbon 31 or the high-efficiency particulate air filter 32 for suppressing viruses, bacteria, and fungus in the polluted gas introduced into the filtering and cleaning assembly 3.

The activated carbon 31 is provided for filtering and absorbing PM2.5, the zeolite mesh 33 is provided for filtering and absorbing volatile organic compound (VOC), and the high-efficiency particulate air filter 32 is provided for absorbing the chemical smog, bacteria, dust, particles, and pollens contained in the polluted gas, thereby the polluted gas introduced into the filtering and cleaning assembly 3 is filtered and purified.

In some embodiments, the filtering and cleaning assembly 3 may be a combination of the activated carbon 31, the high-efficiency particulate air filter 32, the zeolite mesh 33, and a photocatalyst unit 34. In the present embodiment, the polluted gas in the outdoor space is introduced into the filtering and cleaning assembly 3 so as to decompose and sterilize the hazardous matters in the polluted gas through the chemical energy converted from the light energy by the photocatalyst unit 34 and achieve the effect of filtration and purification by the filtering and cleaning assembly 3.

In some embodiments, the filtering and cleaning assembly 3 may be a combination of the activated carbon 31, the high-efficiency particulate air filter 32, the zeolite mesh 33, and a photo plasma unit 35. The photo plasma unit 35 includes a nanometer light tube. The polluted gas introduced by the filtering and cleaning assembly 3 is illuminated by the nanometer light tube, thereby the volatile organic gases contained in the polluted gas can be decomposed and purified. When the polluted gas is introduced into the filtering and cleaning assembly 3, the introduced polluted gas is illuminated by the nanometer light tube, making the oxygen molecules and water molecules in the polluted gas decompose into photo-plasma with high oxidative power for generating a plasma flow which is capable of destroying the organic molecules. Accordingly, volatile organic compounds (VOC) such as formaldehyde and toluene in the polluted gas can be decomposed into water and carbon dioxide. Thus, the polluted gas can be filtered and purified by the filtering and cleaning assembly 3.
